LinqPad - EntityFramework 4.3.1 - MissingMethodException - Sql Compact

I have my POCO model - a separate dll than my asp.net mvc 3 website.

I created a new connection in the LinqPad beta: v4.41.01 the selected option for Poco, provided the path to the custom dll, Chose DbContext, Choice through the constructor without parameters.

This did not work as I am using SqlServer Compact.

Then I created the dummy.config file as follows:

   <?xml version="1.0" encoding="utf-8"?>
   <configuration>
    <configSections>
        <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=4.3.1.0,  Culture=neutral, PublicKeyToken=b77a5c561934e089" />
  </configSections>
  <entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlCeConnectionFactory, EntityFramework">
    <parameters>
      <parameter value="System.Data.SqlServerCe.4.0" />
    </parameters>
  </defaultConnectionFactory>
</entityFramework>
    <connectionStrings>
        <add name="ModelContext"
             connectionString="data source=database.sdf"
             providerName="system.data.sqlserverce.4.0" />
    </connectionStrings>
</configuration>

In this connection test is shown successfully. Even the tree on the left is also populated. But when I run any request, it throws an exception as follows: Method not found: 'System.Data.Entity.DbSet`1 InventoryModelContext.get_xxx ()'.

EDIT . Also note that this seems to be a compilation error!

Any solution or workaround? Am I missing something?
